To all whom it may concern:

Be it known that l, Tnrnox L. Hines, a citizen of the United States, and ILhlLlCIll of Chicago, in the county of Cook and State nf Illinois, have invented -certain new and useful lmpro 'ements in Headlights; and I do hereby doc are that the following description of my said invention, taken in connection with tho act-om anying sheets of drawings, forms a full, c ear, and exact specification, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has general reference to improvements in headlights for automobiles,

launche locomotives, ships, and other vehicles and vessels; and it con-ists, essentially. in the novel and eculiar combination of parts and details of construction, as herein afttr first fully set forth and described, and then pointed out in the claims.

In the drawings already mentioned, which serve to illustrate this invention more fully, Figure 1 a. longitudinal sectional elevation of my improved headlight as used in connection with gas burner. 'Fig. 2 is an elevation of fragment of the said headlight showing details of construction of the adjusting mechanism. Fig. 3 is a perspective view of the tapering adjusting block located on the outside of the shell or casing of this lamp. Figfitis a plan of the reinforemgplate located within the said shell, and Fig. 5 is a perspective view of the adjusting mechanism employed for bringing the source of. li ht into the exact focus of the reflector. Fig. (3 is a longitudinal sectional elevation of this headlight as used in connection with an electric incandesicnt lamp. Fig i' is a sideelevation of the adjusting'niechanism adapt ed for use in connection with an incandescent electric lamp.

Like arts are designated by corresponding sym iols of reference in all the figures.

The object of this invention is the production of an eliicient, serviceable, and convenient headlight forautomubilc and other purpmeslin which a parabolic reflector is employed in cunnw-tiou with (.lllit. an electric. incamlesrent lamp or it gas-burner. lo accomplish this ob iect. I proceed, as follows:

10 in the drawings designates the outer;

casing of this hcadlight. It is, plol'crablv. circular in transverse H'ttilflltilllll tapcring longitudinally. and for the purpo.-e o1 stillcuing this casing, l pl'l-fci' to corrugatc the The forward, larger, end of this casing is closed by a door it, having a glass-front 1;, which glass front is hcl'd in position in the door-frame by a splicring l3, elm-aging an out\vardly-projcctiug bead H, )5 being sprung into the annular groove formed by 'said bead. This door is hinged to the cusing 10. and locked thereto by a catch or similar contrirancc, not shown, in any dc- :;ired manner.

The rear 'end'of the casing 10 is closed by a bottom 20. which is removabl v held in the casing in screws 43 or other convenient means. ll'ithin this casing there l. located a parabolic reflector 15. which has at its open end an outwardly-tlariug flange It}, and it is held centrally within the casing by a ring 15, rcmorably secured t the casing by screws 42. The ring has an annular groove it, which engages the tlaring llan' c on the refiector, an elastic packing of felt, asbestos, or similar material being placed in this groove and surroundin the flange to preventrattling and also rcakago of the reflector. The rear end of this rtiector is sustained in the casing by a diaphragm .21, having an outwardlrflaring flange engaging the curved back of said reflector, an elastic ring or packing 23, being interposed between said flange 2:3 and the back of the rcflector for the same purpose as the packing. 23 at the forward end of the reflector.

The device thus far described illustrated in Fig. 1, but where cheapness of construe"- the diaphragm 21 and form in the bottom 20 a flaring member 22, as shown in Fig. (3', a s nice 57, behind the reflector 15 being proriued to protect the latter from injury or breakage.

42 is a source of light, being either a filament of an electric, incandescent, lamp, or a gas or acetylene-gas burner. It is surroundcd by a glass protector 36. which in the case of an incandescent electric lain is its glass bulb; but in the event of a gas nirner being med. it is a glass chiuuiey, as illustrated in Fig. 1, said glass protector being employed to prevent l at from allot-ting the reflector. This source ofv lightis mounted upon a so ket 27. and the latter secured to'a tubular member 26. which member is scrm threaded at its upper end for this purpose. The luwcr mid of this tubular member is also screwt threaded to engage an cxtcriorly screwtion is a desideratuln, I may dispense with same, as clearly illustrated in the figures; I

The tubular inenihr-r .Zt' panees through the f-ilt' ll. the reinfotclog-plate ill. anrl the upper lll t'li 2 -2. an i it has at its lowt-r end lurk-nuts 41 f r the objeet which will hereinafter more fully appear.

ln ortler to pass the tubular tttt'tttltt't' 2t and it's sot-ket 27 into the reflect r. I provide an opening :24 therein and to a tt'ord exit of heated air, I may provide the same with an exit-opening 217. all as clearly shown in Figs. 1 and t.

It will now the eleetrie llt'ftllttltx'clll lamp vertically into the headlight. the vertical vibrations of a ear. ship. or other vehicle or vessel will not seriously allert the filament and prevent lH'L'ttlU-lglt thereof.

In order to adapt this'la-adli zht for use in eonnection with illuminating gas. I serew 4t anti it has a lo4-l-:nut 45 below be olwert'etl that by lorating I l l i I l l i l l E i t l l l l 52 all easing r:
